Solution:
1. Given expression:400 \div 50 \times 4 + 4
2. We want the result to be 1. Look at the expression and determine how to place parentheses to achieve the desired result.
3. Try placing parentheses around the division and multiplication first:
400 \div (50 \times 4) + 4
4. Simplify inside the parentheses:
50 \times 4 = 200
5. Substitute back:
400 \div 200 + 4
6. Divide first:
400 \div 200 = 2
7. Add:
2 + 4 = 6
8. This does not give the desired result of 1. Try placing parentheses differently:
400 \div (50 \times (4 + 4))
9. Simplify inside the innermost parentheses:
4 + 4 = 8
10. Substitute back:
400 \div (50 \times 8)
11. Multiply:
50 \times 8 = 400
12. Substitute back:
400 \div 400
13. Divide:
400 \div 400 = 1
14. Therefore, the correct placement of parentheses is:
400 \div (50 \times (4 + 4)) = 1
